The invention relates to a permanent waving device for the hair whichcomprises an electric heating element contained in a casing and a haircurler inserted in the said casing, and is so adapted as to facilitateready connection of the hair curler carrying the hair coiled on it tothe casing. This connection is effected according to the invention bymeans of an impaling pin screwed into a plate made of insulatingmaterial, which is hingedly connected to the casing and is pressed by aspring against the end face thereof; it being possible to provide thisimpaling pin with a heating element also so that the hair curlercarrying the hair coiled upon it is also heated simultaneously. Inaddition, the entire casing is so constructed as to form a closedheating chamber so that the vapour issuing from the moist hair cannotescape, whereby a more rapid and more complete preparation of the hairis attained. In order that this chamber shall not open inadvertently andthat the person whose hair is being waved shall not be injured byburning due to such undesired opening, a locking device is provided toensure the connection between the hair curler and the casing containingthe electric heating element.

A constructional example of the invention is shown in the accompanyingdrawing, wherein Figure 1 shows a longitudinal section through thecomplete device.

Figure 2 is an end elevation.

Figure 3 shows in elevation the impalement of the hair curler.

Figure 4 is a View in perspective of the locking device.

The casing 1 which has the usual horse-shoe shape is connected by thehinge 2 to the plate 3 made of insulating material. A supporting plate4, likewise of insulating material, is fixed to the casing 1 at acertain suitable distance from the wall 3. Between the plates 3 and 4 isprovided a helical spring or the like 5 which presses the plate 3 into aposition in which it bears against the end face of the casing 1, asshown in Figure 1. The impaling pin 6, the diameter of which correspondsto the bore 7 of the inner element or hair curler 8 is suitably fixed tothe plate 3. The hair curler 8 is constructed in the usual way. Theimpaling pin 6 is so fixed to the plate 3 as to extend substantially inthe middle of the horseshoe shaped cavity of the casing 1. The curler 8is attached to the plate 9 which consists of insulating material and isso dimensioned as to which the external shield 10 projects over the endopening of the casing 1, thereby closing the latter entirely. Thus,thorough closure of the chamber formed by the casing 1 and the plate 9is obtained by means of the shield 10, the extension 9 of the plate andthe ledges 9", so that the vapour ascending from the hair cannot escapeand a more rapid and more complete waving of the hair is obtained. Thecurler 8 is connected to the casing 1-after coiling the hair on thecurlerby pressing together the ends of the plates 3 and 4 at the placeof the spring 5 to bring the plate 3 into the position shown in Figure 3and then impaling the curler 8 on the pin 6. By releasing the pressureon the ends of the plates 3 and 4, the curler then comes automaticallyinto the cavity of the casing l, by turning down, without it beingpossible to damage the hair.

The impaling pin 6 may with advantage also be provided with a heatingelement and may be connected either independently to the correspondingcurrent lead or to the current lead of the heating element contained inthe casing 1, which is readily effected since the impaling pin 6 isintegral with the casing 1. In this case, normal and light hair curlersmay be used with which the work can be carried out much moreconveniently and more surely than with heavy curlers adapted for directheating.

The locking device ensuring the mutual position of the hair curler 8 andthe casing 1, in the example shown, is arranged in the wall 3 and at theside thereof, and comprises the bolt 12 adapted to slide into the recess13 and secured by the plate 14. The spring 15 in the bore 16 presses thebolt downwardly into the position in which its end projects into theopening 17 provided in the extension 9 of the plate 9, thus preventingthe hair curler 8 from slipping oif the impaling pin 6 in an undesiredmanner. The locking device is released by lifting the bolt 12 by the lug12 against the pressure of the spring 15.

.Of course, the locking device described is merely an example and may bemodified and attached in any place without departing from the scope ofthe invention.

Iclaim:

A permanent waving device for the hair comprising an electrically heatedcasing and a hair curler inserted on an impaling pin in said casing,characterized in that the impaling pin is screwed into a plate made ofinsulating material which is hingedly mounted with respect to theheating cas- 7 ing and is pressed by a spring against the end facethereof.
